VACUUM-CREATING DEVICE.

Specification of Letters Patent.

Patented July @5, 1915..

Application led September 4, 1912. Serial No. 718,474.

To all whom t may concern:

Be it known that I, GEORGE C. VVErss, a citizen of the United Sta-tes, residing at Pittsburgh, in the county of Allegheny and lState of Pennsylvania, have invented new and useful Improvements in Vacuum-Creating Devices, of which the following is a specification.

The invention relates to that class of inventions known as vacuum cleaners, and has for an object to provide a hydraulically operated device for producing suction.

rI`he invention embodies, among other features, a device that is preferably mounted in the cellar or basement of a building and connected with a suitable water supply pipe whereby, through the action of the water in passing through the casing of the device, a sutlicient suction will be produced to permit of picking up and carrying away particles of dust or dirt in the other rooms of the house or building, suitable stand pipes being provided for connection with the device in the basement of a building, whereby, through the medium of a hose, access can be had to the nools and corners of the various rooms, the suction being produced at the nozzle end of the hose and of suiiicient strength to take up and carry into the hose through the nozzle end thereof the dirt or dust in the rooms.

In the further disclosure of the invention reference is to be had to theaccompanying drawings constituting a part of this specification, in which similar characters of reference designate corresponding parts in all the views, and in which:

Figure 1 is a `fragmentary sectional view of a building showing my device mounted in the basement thereof, and having connection with a suitable stand pipe arranged to eX- tend through the building; Fig. 2 is a vertical longitudinal sectional view of the device; Fig. 3 is a front elevation of the device, parts being broken away to disclose the underlying structure; Fig. 4 is a horizontal sectional view taken on the line 4-4 inFig. 1; Fig. 5 is a horizontal sectional view taken on the line 5 5 in Fig. 1; and Fig. 6 is a horizontal sectional view taken on the line 6 6 in Eig. 1.

Referring more particularly to the views, I employ a tubular casing 10, preferably consisting of a series of connected sections 10a, 10b and 10, the section l()a at the upper central end thereof having connection with a suitable water supply pipe 11. a stand pipe 12 being connected to the section 10a adjacent the supply pipe 11 and spaced there.

from, the mentioned stand pipe being adapted to extend from one floor to another in abuilding 13 and` provided with a suitable tap 14, one tap beingarranged at each floor in order that a hose 15 can be connected to oneI of the taps 111,'. said hose being preferably provided with a nozzle 16 at the upper `open end of which the suction is produced.

Adjacent the connection of the supply pipe 11 with the section 10a and in vertical alinement therewith, a frusto-conically shaped nozzle 17 is arranged to depend in the section 10, a second nozzle 18 being formed with or vsuitably secured within the section 102L at the lower end thereof, at the point where the section 10n connects with the section 10b, a similar' nozzle 19 being formed with or secured within the section 10b at the upper end thereof so that the lower end of the nozzle 18. will abut against and aline with the nozzle 19 when the sections 1()a and 10b are secured in abutting position, each of the nozzles 18 and 19 being frusto-conical in shape and when connected constituting a double nozzle, the mentioned double nozzle being in vertical alinement with the nozzle 17.

|Ihe section 10c consists substantially of a circular casing 20 in which is journaled a paddle wheel 21 having paddles 22 thereof arranged to project into a passage 23 formed in the/casing 20, a pipe 21 being provided to connect the sections 10b and 10, said pipe being arranged in vertical alinement with the nozzle 17 and the double nozzle consisting of the single nozzles 18 and 19, a discharge opening 25 being formed in the lower end of the casing 20 and a hood 26 being mounted to contact with a side of the casing and having connection with a tubular extension 27 of the section 10b, the upper end of the tubular extension 27 being connected with a tubular extension 28 formed with the section 10a, a series of apertures 29 being provided in a side of the casing 20 to connect the chamber formed by the hood 26 with the chamber formed by the casing 20 as shown in Fig. 3. Suitable valves 30 are mounted on the sections 10a and 10b, said valves being manually operable to admit air to the sections 10'r1 and 10b for the purpose of increasing or decreasing the suction in the mentioned sections, it being readily apparent that when the valves 30 are open the suction Will decrease and When the valves are closed the Vmaximum amount 4of suction Will be produced, it being further seen that the rotation of the paddle Wheel 21 in the casing `2O will create a suction in *the chamber -formed by the hood 26.

In the use of the device described, Water is admitted into the casing 10 through the .pipe y11 and it will be readily seen vthatthe Water Will pass through the casing in a continuous stream, this stream being kproduced and formed by thefnozzles 17, 18 and 19'inthe casing, it being yfurther seen that ,thev nozzle 17 .is spaced from the nozzles 18 and 19 to form passages 10d between the upperendof the nozzle 18 and the upper*v end Vof the casing 10, similar passages 10e being vformed between the lower endof the lnozzle 19-and the lower endof the casing 10 so that -wvhen the .stream of lWater passes `through the casing, sufiicient suction Will beproducediat the upper end of the nozzle 16,of,the hose 15to take upany dust or dirt l. in one ofthe roomsoithe building and convey the same tothe casing A10, the .suction .being suiiicient to carry-the accumulated dust or dirt throughzthe casing and out through the discharge opening 25, .it being further seen :that @the y*rotation .of the Y paddle Wheel 21'.in the casing 2O -Will produce a suction in.thefchamberf;formed by the hood 26 and in thefextensions 27 2S to carry some of the accumulated dust or dirt through the eX- .tensions 27, 28 intothe hood 26, from Which,

through -the rotation of the paddle Wheel 2l, lthe accumulated matter will be carried by -the-Waterfthrough the discharge opening 25, a suitable pipe being preferably provided .at :thedischarge opening 25 to connect the section .10c .With a sewer -or other Waste receiving receptacle.

A vdevice ofthe character described can befconveniently connected with the usual 1vvater-supply pipe of an ordinary building and as disclosed in Fig. 1, the hose 15 can be readily connected to any of the taps 14.-

-for the purpose ofvtakingaway the dust or -nozzles independently .mounted lin the said casing and .arranged ,in .vertical alinement with thelsaid'water.supply=pipe,and extensions formed with vthe said sections, adjacent .extensions bemgconnected to form a passagezin the said casmg, said rpassage being independent ofa second passage formed bythe saidnozzles in the said casing.

2. In a devicelof the class described, the combination with a casing consisting of a series of connected sections, olf-means in the .said casing forreceivi-ng a stream of Water :from a supply pipeconnected to the casing andv conveying .the same 4through .the casing,

a paddle Wheel mounted in one of the sections of tlievcasing and adapted .to Abe engaged zby y the stream lof YWater to :impart rotation tothe paddle wheel, and extensions vformed .on the said sections, adjacent ex- ;tensions being connected to form a passage from the upper end of the casing to the said ipaddle -Wheel.

In testimony whereof I aliix vmy signature inpresence of two witnesses.
